In math we made a desmos self portrait. We had to use equations and functions to make it.
I used linear functions, quadratic functions, absolute functions and two types of circles to make my self portrait. I used absolute functions for some of the clothing, linear functions for part of the neck, circle relation for part of the ears, the conic section circle for the eyes and quadratic functions for everything else. To move the lines I added a negative or positive sign in front of the x or y to flip it. Put either the x or y into brackets and add or subtract a number in the brackets and maybe added an exponent to move it left and right. Added a positive or negative sign on the numbers around the x or y to move it up or down. And/or made the number bigger or smaller in front of the brackets if its a quadratic function to have it have a larger or smaller slope.
For this project I used both my critical and creative thinking. I used my creative thinking to think of using my bitmoji as a baseline and template to make my self portrait and what types of lines would work in certain areas. I then used my critical thinking to figure out how to then manipulate the lines to make them make the right shape and what order to create the portrait. I first started with the eyes, then the eyebrows and the rest of the face. I then did the head and hair and moved onto the ears and neck. I then finished by doing the clothing. My main challenge was doing the ears so first I tried trial and error. Then I used my creative thinking to use the circle relations and just restrict them for the bottom and then use quadratic functions for the rest of it. I did get some help from my teacher at the beginning to help me with the lines and how to write some of them. I think that this assignment helped me understand functions, relations and graphs because I learned how I would graph a absolute value and a circle relation.
